The Sheffield Carols (as they are popularly known) date back a long time before the so-called folk revival and are not part of it. I say so-called because like a lot of traditional singing they never went away, and whilst they now have a new lease of life they have not been "revived" as such. I am indeed a newcomer to folk music having only been listening to it since 1960.

Billy Mills - a long-time singer at Dungworth who died aged well past 80, and who most people would recognise as a traditional singer, used to sing "Christmas Tree". The words he sang were in part a mish-mash of misheard lyrics - but Bill sang it that way consistently all the years I knew him.

Were those the wrong words? And whose words were the right words? The one in the printed version? How do you know their version is "right" and the song Billy sang is "wrong"?

Holmfirth Anthem is sung in different ways in a lot of the pubs in the Sheffield area, come and tell some of them they are getting it wrong Dick.

I suspect the answer will be short.
